Abstract |
Respirable dust samples were collected on 25mm diameter Gelman VM-1 filters and were analysed directly with infrared radiation without any sample preparation. Field samples analysed using this method, redeposited infrared, and x-ray diffraction methods correlated well in the range 13-194µg. The direct infrared method is quick and simple and crystalline phase variants of free silica (quartz and cristobalite) appear to be distinguishable with infrared spectrophotometry. |
